Abstract
A method and apparatus for combustion of a liquid fuel and oxygen which produces a fishtail or fan-shaped flame configuration.
Claims22
An oxy-liquid fuel burner comprising:
- a liquid fuel conduit having a liquid fuel inlet end and a liquid fuel discharge end;
- an oxygen conduit disposed around said liquid fuel conduit and forming an annular region between an exterior surface of said liquid fuel conduit and an interior surface of said oxygen conduit;
- said liquid fuel conduit comprising atomization means for atomization of a liquid fuel and shaping means for discharging said liquid fuel from said liquid fuel discharge end in an outwardly divergent, fishtail configuration;
- and
- said oxygen conduit comprising means for discharging oxygen in an outwardly divergent, fishtail configuration corresponding to said liquid fuel configuration and substantially encircling said liquid fuel.
2 more elements
A method for combustion of a liquid fuel, said method comprising the steps of:
- atomizing said liquid fuel;
- discharging said atomized liquid fuel from a liquid fuel conduit, said discharged atomized liquid fuel having an outwardly divergent, fishtail configuration;
- and
- discharging oxygen from an oxygen conduit surrounding said liquid fuel conduit, said discharged oxygen encircling said outwardly divergent, fishtail configuration of liquid fuel, thereby forming upon ignition a liquid fuel flame having an outwardly divergent, fishtail shape.
1 more element
In an oxy-liquid fuel burner which is attachable to a burner block having a burner block inlet and a burner block outlet and a communication between said burner block inlet and said burner block outlet, the improvement comprising:
- means for atomizing and injecting a liquid fuel into said burner block inlet, whereby said atomized and injected liquid fuel has an outwardly divergent, fishtail configuration;
- and
- oxygen means for injecting oxygen into said burner block inlet, whereby said oxygen encircles said atomized and injected liquid fuel, thereby forming upon ignition a flame having an outwardly divergent, fishtail configuration downstream of said burner block.
